How do I get the default Weather app and widget on my LG G Stylo back?

[Android Central Question]

The Weather Theme has disappeared from my home screen. The app appears in the list of apps under Apps in Settings, but not in the list you select from the home screen (the icon with the six dots that's supposed to show you every interactive app on your phone). The widget disappeared from the list as well. I went to the apps (Weather Service and Weather Theme) but "disable" was greyed out in Weather Service (I wanter to disable and then re-enable it) and "Uninstall" in Weather Theme only allows for deleting it (as opposed to disabling and resetting it to its factory settings).

Welcome to Android Central! Did this happen after a system update? Phone manufacturers can sometimes add, delete, or modify preinstalled apps as part of a system update (without warning you beforehand).
